  • This would vary based on what router you use, but this is the way I handled it on my Ubiquity EdgeRouter.


    • I added a DHCP reservation for my TV so it’s IP address on my local network doesn’t change.

    • I added a new firewall policy (with the highest priority) that accepts all traffic by default between my internal LAN network and the WAN interface of my router.

    • Then I added a rule to that policy to drop traffic from the IP address I assigned to my TV.

    Now the TV can no longer phone home to send obnoxious notifications or issue surprise firmware updates but I can still turn on the TV and adjust the volume over the local network. I use Home Assistant for this, but I think the LG remote android app would still work as well.
